I created several custom game engines but I forgot their features. Is there a way to look their features or not?
I don't know of any direct way. Though if you want to find out after the fact, I propose to develop a small game, all parts you added to your old engine will be available for you to select as feature. Of course for that you have to actively create a game, but you can write the available features down at this time and have the knowledge available for next time.
- Always put meaningful names there to identify different Engines.
- Also: If you select: Create new Custom Engine, You see the items you selected previously (of course this only works for Engine you created last time).
